ObjectivesObjectivesSPI 0707.7.1 Can I describe and

classify the physical properties of minerals?◦What is a mineral?

◦How are minerals classified?

Candy Mineral Classification Look at the classification chart

for minerals. With your group, develop a

system for classifying candy “minerals” based on their observable physical properties.

7 Ways to Identify Minerals:1. _________: can be used to

identify minerals; however, the same mineral can come in a variety of colors.

Challenge QuestionIs color the best way to identify

a mineral? Why or why not?

Color

7 Ways to Identify Minerals:2. _________: the way a surface

reflects lightTypes of Mineral Luster Metallic: bright, reflective Submetallic: dull, reflective Nonmetallic: vitreous (glassy), silky,

resinous (plastic), waxy (greasy), pearly (creamy), earthy (rough)

Challenge QuestionIs luster the best way to identify

a mineral? Why or why not?

Luster

7 Ways to Identify Minerals:3. _________: the color of a mineral

in powered form A mineral’s _________ can be found by

rubbing the mineral against a piece of unglazed porcelain called a __________ _________.

The mark left on the streak plate is called the __________.

Challenge QuestionIs the mineral’s streak color the

same as the color of the mineral? Why or why not?

Streak

Each pair chooses one of three identification methods we have taken notes on so far, and teach your partner about this way to identify a mineral. Take turns and be good listeners! You have 2 minutes!

7 Ways to Identify Minerals:4. _____________: different types of

minerals break in different ways _________ is the tendency of some

minerals to break along smooth, flat surface.

_________ is the tendency of some minerals to break unevenly along curved, jagged, or irregular surface.

Challenge QuestionWhat determines the way

minerals break?

Cleavage & Fracture

CleavageFracture

7 Ways to Identify Minerals:5. _____________: a minerals

resistance to being scratched To determine the hardness of minerals,

scientists use the ______________________.

The _____________ the mineral’s resistance to being scratched, the ___________ the rating.

Mohs Hardness Scale ranges from ___________ to _____________.

Challenge QuestionWhat is the only mineral that

can scratch a diamond?

Hardness

Mohs Hardness Scalegreater

higher1 (softest)

10 (hardest)

7 Ways to Identify Minerals:6. _____________: the measure of

how much matter is in a given amount of space (volume) Formula for density: D = m (broken

heart)

Challenge QuestionWhat science tool would we use

to measure the mass of the mineral? Volume?

Density

v

7 Ways to Identify Minerals:7. _____________: characteristics about

a mineral that only a few minerals have (or sometimes it is the only mineral that has that trait).Examples: Fluorescence Chemical Reaction Magnetism Taste

Challenge QuestionHow can you tell if a mineral has

the property of fluorescence?

Special properties
